Small toe deformities are bent lesser toes that rub on footwear and form corns. They start flexible and, untreated, become fixed. While the toe is still flexible, footwear changes and exercises help; a fixed, painful toe is corrected surgically, which is highly effective.
Symptoms
- A toe bent at a joint, rubbing on shoes
- Corns on the knuckle or tip
- Three patterns: hammer (middle joint), claw (middle and end joints), mallet (tip joint)
- An advanced toe can ride over or under its neighbour
Causes & risk factors
- Toe muscle imbalance
- Tight, pointed footwear and high heels
- An associated bunion crowding the second toe
- A high-arched (cavus) foot
- Neurological conditions or rheumatoid arthritis
Conservative treatment comes first
- A deep toe-box shoe
- Gel sleeves and foam pads
- Podiatry to reduce corns
- Toe-strengthening exercises while the toe is still flexible
- The corn is the symptom — unless the toe position is addressed, it recurs
When surgery is considered
A flexible hammer or mallet toe is treated with a tendon transfer that keeps it mobile; a fixed hammer toe is reshaped or fused straight for durability; a claw toe with a dislocating joint needs a joint release, plantar-plate repair and Weil osteotomy. Mostly day-case — normal footwear at 6–8 weeks, swelling settling over 3–6 months.
Questions & answers
A flexible toe can improve with early treatment, but a deformity rarely corrects itself once established.
The corn is caused by the bent toe pressing on the shoe. Until the toe position is corrected, the corn recurs.
Yes, they are often treated in the same operation, as a bunion frequently drives the neighbouring hammer toe.
Full specialist guide
Small toe deformities — including hammer toe, claw toe, and mallet toe — are common structural abnormalities of the lesser toes in which one or more toe joints become stuck in a bent position, causing the toes to rub on footwear, develop painful corns and calluses, and in advanced cases become fixed and rigid. The deformities are often associated with bunions, high arches, or ill-fitting footwear and tend to progress over time. Conservative management with footwear modification and toe splints controls symptoms for many patients. When conservative measures are insufficient or the deformity is fixed, surgical correction is highly effective. Our specialist team in Milton Keynes and Northampton offers the full treatment pathway.
Small Toe Deformity: Hammer Toe, Claw Toe, and Mallet Toe Explained
Small toe deformities are among the most common foot conditions encountered in orthopaedic practice. They are frequently dismissed as cosmetic concerns, yet for many patients they cause significant pain from footwear friction, make shoe-fitting extremely difficult, and progressively worsen over time without appropriate intervention. Understanding the three main deformity types, the factors that drive their development, and the treatment options available enables informed decisions about management.
At Mercury Foot and Ankle, our specialist team provides expert assessment and treatment of all small toe deformities at The Saxon Clinic, Milton Keynes and Three Shires Hospital, Northampton.
The Three Main Deformity Types
The three classic small toe deformities differ in which joint of the toe is primarily affected:
Hammer toe is the most common deformity, primarily affecting the proximal interphalangeal (PIP) joint — the middle joint of the toe. The toe adopts a characteristic bent appearance at this joint, with the tip of the toe pointing downward. It most commonly affects the second toe. In early stages the deformity is flexible and the toe can be passively corrected to a straight position; in advanced stages it becomes fixed (rigid).
Claw toe involves both the PIP joint (flexed, as in hammer toe) and the distal interphalangeal (DIP) joint — the small joint nearest the tip of the toe — which is also flexed. Additionally, the metatarsophalangeal (MTP) joint — where the toe meets the foot — is hyperextended. This combination of hyperextension at the MTP joint and flexion at both IP joints produces the characteristic claw shape. Claw toes frequently affect multiple toes simultaneously and are associated with neurological conditions including Charcot-Marie-Tooth disease and with high arch (cavus) foot deformity.
Mallet toe affects primarily the DIP joint — the small joint nearest the toe tip — which becomes fixed in a flexed position. The tip of the toe curls downward, producing a characteristic corn on the tip of the toe and often also on the dorsum of the DIP joint. It most commonly affects the second toe.
Causes and Risk Factors
Small toe deformities arise from an imbalance between the intrinsic muscles of the foot (the small muscles within the foot that extend and stabilise the toes) and the extrinsic muscles (the longer muscles of the leg that flex the toes). When the intrinsic muscles are weakened or their action is disrupted, the extrinsic flexors pull the toes into flexion without adequate opposition.
Contributing factors include:
Ill-fitting footwear — shoes that are too short, too narrow, or have a pointed toe box force the toes into a cramped position that, over time, encourages the development and progression of deformity. High heels transfer load to the forefoot and hyperextend the MTP joints, predisposing to claw toe formation.
Associated foot deformities — bunions (hallux valgus) are strongly associated with second-toe hammer toe, as the deviated big toe crowds the second toe into a flexed position. High-arched (cavus) foot is strongly associated with claw toe deformity.
Neurological conditions — Charcot-Marie-Tooth disease, cerebral palsy, and stroke can produce claw toe deformity through disruption of the normal muscle balance in the foot.
Inflammatory arthritis — rheumatoid arthritis causes MTP joint synovitis that destroys the plantar plate and intrinsic musculature, producing characteristic MTP subluxation and claw toe deformity.
Genetics — a family tendency to small toe deformity is very common.
Symptoms and Complications
The primary complaint is pain from footwear friction over the prominent joint. A dorsal corn — a hard thickening of skin — forms over the apex of the bent PIP joint and is a constant source of irritation in shoes. A corn at the toe tip occurs in mallet and claw toes where the tip is in contact with the floor or shoe. Interdigital corns (soft corns) form in the web spaces between toes where adjacent bony prominences rub together.
Patients with claw toe deformity frequently develop prominent, painful metatarsal heads under the forefoot — the MTP hyperextension pulls the protective fat pad forward, leaving the metatarsal heads exposed to direct ground pressure. This produces metatarsalgia — ball of foot pain — as a secondary complication.
In advanced cases, the MTP joint subluxes (partially dislocates) or fully dislocates, with the toe crossing over or under adjacent toes. This stage is significantly more challenging to correct surgically.
Conservative Treatment
Footwear modification is the first and most important intervention. The shoe must have sufficient toe box depth — vertical space — for the bent toe to sit without rubbing. Many patients with small toe deformities find that a deep, wide shoe with a rounded toe box eliminates the majority of their symptoms. A shoe that is longer than the affected foot's length may also help, though this compromises fit elsewhere.
Toe splints and padding — a gel toe sleeve, foam pad, or toe prop under the flexed DIP joint reduces the tip contact pressure that drives corn formation. These do not correct the deformity but significantly reduce the day-to-day friction symptoms.
Corn treatment — regular gentle filing of corns with a pumice stone after bathing reduces their bulk and the associated pain. Corn plasters containing salicylic acid soften corns and can be helpful. Formal podiatry debridement of corns is appropriate for patients who find self-management difficult. Important: the corn is a symptom of the underlying deformity — managing the corn without addressing the deformity means it will always return.
Intrinsic muscle exercises — toe-scrunching, towel pick-up, and marble-pick-up exercises maintain intrinsic muscle function in flexible deformities and may slow progression.
Surgical Treatment
Surgery is indicated when: deformity is causing significant pain or difficulty with footwear despite adequate conservative management; the deformity has become fixed (rigid) and cannot be passively corrected; or the MTP joint has subluxed or dislocated.
For flexible hammer or mallet toe, a flexor tendon transfer — re-routing the flexor digitorum longus tendon from below the toe to the top — corrects the joint balance and allows the toe to straighten while preserving joint mobility.
For fixed hammer toe, a proximal interphalangeal joint arthroplasty or arthrodesis is performed. Arthroplasty removes a small segment of bone from the joint to allow the toe to be passively straightened. Arthrodesis fuses the PIP joint in a straight position, providing more durable correction for rigid deformity.
For claw toe with MTP subluxation, additional procedures addressing the MTP joint are required — including MTP joint release, plantar plate repair, and Weil osteotomy (shortening the metatarsal to decompress the MTP joint).
Small toe surgery is typically performed as a day case. Recovery involves a period in a wide post-operative shoe with gradual return to normal footwear at 6 to 8 weeks. Swelling in the operated toes can persist for 3 to 6 months.
Frequently Asked Questions
Will my bent toe straighten on its own?
Flexible deformities can be encouraged to improve with early intervention, but spontaneous correction without treatment is rare. Fixed deformities do not correct without surgery.
Should I address the bunion and the hammer toe at the same time?
Where a bunion is causing the second-toe hammer toe, it is often appropriate to address both deformities in the same operation. Your surgeon will plan the procedures based on the specific deformity pattern and your priorities.
What is a corn and how is it different from a callus?
A corn (clavus) is a localised, painful thickening of skin with a hard central core, caused by focused pressure over a bony prominence. A callus is a broader, more diffuse area of thickened skin without a central core, caused by more distributed friction. Corns over toe deformities are a very common presentation that drives patients to seek treatment.
